Contributing factors are often subtle and complex. Internally, a repeating limbic reaction causes the actual involuntary tightness.
Causes of Vaginismus
For most women, vaginismus comes as a surprise. Though they are usually biologically normal, difficulties with penetration or ongoing vaginal tightness and pain seem to start mysteriously and continue repeatedly. The contributing factors are subtle, and not always easily identified. Consider:
- Women who have had years of normal, enjoyable intercourse, yet start having ongoing pain or discomfort with sex after a brief and minor medical issue.
- Young couples that are blind-sided when they are unable to consummate their marriages.
- Young women who hopelessly struggle and fail at tampon insertion, yet have no discernible life experiences to blame.
Fortunately, not knowing the specific causes will not impede recovery unless there are other coexisting pain-causing issues that require simultaneous medical treatment to be able to progress with vaginismus resolution (see below).
One of the reasons that vaginismus is so often misdiagnosed is that physicians first look for obvious cause-and-effect explanations, but vaginismus doesn't always have apparent causes. Another is that patients tend to shy away from bringing embarrassing medical attention to sexual problems when asked. It is frustrating when our bodies don't respond the way we want, and it can be so difficult to explain.
How the Limbic System Causes Vaginismus
The limbic system is a group of structures in the brain that work together to help regulate emotions, memories, arousal, and reactive body functions. Though normally very effective, life experiences can be internalized in such a way that the limbic system starts causing the body to respond in unhelpful ways.
For example, if a child tossing a ball with a friend accidentally gets hit in the face, the next time she sees a ball coming at her she may reflexively turn her head, close her eyes, and brace for impact Instead of simply catching the ball. You might say her limbic system had become 'programmed' to make unhelpful responses.
Below, we list many examples of life experiences that may similarly 'program' the limbic system to react incorrectly during intimacy and trigger vaginismus. When the sensory system detects various forms of touch, pelvic vulnerability, or the anticipation of penetration, the limbic system signals the body to tense up internally as a protection mechanism. It mistakenly alerts the body to danger, causing the vaginal muscles to tighten and, thus, interfere with sex. Not only that, but also to terminate the feelings and buildup of sexual arousal.
Some physicians describe vaginismus as a fight or flight reaction in the pelvic floor and surrounding musculature. The muscles are not permanently tightened – they tighten when the limbic system sounds the alarm, then return to normal when the concern is over.
However, the cycle of tightening tends to repeat in a perpetual, ongoing basis until the problem is properly treated and resolved (see The Cycle of Pain, below).
Emotional anxieties, or unhealthy sexual messages, can contribute to and reinforce the initial symptoms of vaginismus, but so can a pelvic pain experience (simply any pain experience in the pelvic area, or a sexual pain experience). Something as simple as a childhood urinary tract infection could start an issue in the limbic system where vaginal pain will be felt again. There may be numerous emotional anxieties like this, from deep-seated emotions to distant memories of pain or fear associated with those parts of the body or with sexual activity in general.
Here is a sample list of wide-ranging experiences that could contribute to developing the vaginismus condition:
Fear, Anxiety, Shame, or Embarrassment

No explanation for condition
- Vaginismus does not always have an obvious cause. Sometimes women with near-perfect childhoods, great relationships, no physical problems, and few anxieties, have trouble identifying a trigger to their vaginismus. The cause might remain a mystery even after vaginismus is fully resolved.
Life experiences vary dramatically from person to person. These experiences might trigger vaginismus in some women but not in others. If, in reviewing your life, you remember unresolved trauma, professional counseling may be beneficial to your mental health.
With vaginismus, the mix of various experiences – such as those examples listed above – cause the limbic system to be in a heightened state of concern and to respond incorrectly to normal, healthy activity. The body response then develops into an entrenched vaginismus condition through a cycle-of-pain experience:
Understanding the Vaginismus Cycle-of-Pain
1. Anticipate Pain: Various life experiences can cause the limbic system to be in a heightened state of sensory reactivity toward the possibilities of pain or danger to the pelvic area. Intercourse, touching, or pelvic vulnerability might trigger the body's limbic alarm.
2. Involuntary Reaction: The limbic alarm causes the body to react incorrectly by tightening up the vaginal muscles to protect itself from potential pain or harm from a person or object.
3. Painful Sex: With the vaginal muscles in a tightened state, sex is uncomfortable or painful between a couple or partners. Penetration might be difficult or even impossible, depending upon the severity of the tightness of the woman.
4. Pain Reinforces: Attempts at sex result in discomfort, pain, or failure, and these experiences further reinforce and "validate" the limbic system's need to continue reflexively reacting and protecting the body.
5. Bracing: The body continues to react with intensifying concerns, strongly tightening to protect itself against any further pain or discomfort. Any attempts at intercourse are met with immediate muscular bracing and ongoing tightness across the pelvic floor and body.
6. Avoidance: Ongoing failure, pain, and discomfort have the effect of greatly diminishing the desire to be sexually intimate. Ultimately, sex avoidance results between a couple or partners. Forced attempts at sex only serve to repeat the same cycle again. The negative experiences fully entrench vaginismus in a woman, and without treatment resolution, the body will stay in this state of limbic response and failure.
Vaginismus is NOT the Sufferer's Fault
The limbic alarm that causes the vaginismus cycle-of-pain can be triggered by any mix of physical and non-physical experiences sometimes going all the way back to childhood experiences. Vaginismus is not the woman's fault and is not intentional—the tightening occurs without conscious direction and often without awareness of the woman. The limbic system reacts by itself, to where the sufferer cannot simply stop the reaction without a resolution treatment process.
It is incredibly frustrating to be unable to physically engage normally.
Vaginismus caused by Other Medical Conditions
Vaginismus is often a complicating factor in the recovery process from other pelvic pain conditions. Vaginismus may co-exist with other medical conditions, triggered by direct pain or heightened anxiety about the continuation of sex potentially causing discomfort, pain or damage. When the original condition has been resolved or managed, yet ongoing tightness and discomfort remains, it is typically due to vaginismus.
In cases where there is clearly both vaginismus and another pelvic medical problem existing simultaneously, both problems need to be treated to ensure full resolution. Without addressing the original medical issue, it will be difficult to resolve vaginismus as it may continue to be triggered by pelvic pain from the other problem. Conversely, after the original pain condition has been addressed, the ongoing problem of vaginismus will also need to be treated.
For example, a woman who undergoes pelvic cancer surgery may have heightened underlying anxiety about her body not being fully healed from the stitches where an incision was made. The anxiety is less emotional and more of a complex body memory of recent trauma and tissue recovery pain. The limbic system senses the mix of general physical and internal emotional anxiety, which involuntarily causes the muscles in the pelvic floor to partially tighten to protect the vaginal area from pain or damage, especially when attempts to resume intercourse begin. The partially tightened muscles cause intercourse attempts to be uncomfortable or painful, increasing the limbic system reaction response and making the body overreact in the future with even greater tightness—an ongoing cycle-of-pain.
There are countless situations of vaginismus and other medical conditions, ranging from the young mother recovering from labor trauma to the mature woman with age-related conditions. The body acts in limbic response when it perceives that penetration is not safe, even though the original physical or medical condition may have been fully resolved.
Overcoming the Limbic Reaction
Fortunately, vaginismus is fully treatable. Women can gain control over their vaginal muscles and override the limbic system reaction that causes the tightness. Recovery from vaginismus means having unhindered, normal sexual intimacy and pleasure.
